Hi and Welcome to the Forums!
Clearing the application cache may help:
1. Open App World
2. Go to My World
3a. For keyboard-based BB's -- Hold down the ALT key and then press, in sequence R, then S, then T
3b. For Storm/Pearl -- Hold the num-lock (!?123) button so it locks and then press, in sequence 3, then 4, then (
4a. If your BB locks after issuing the cache clear, perform a battery pull reboot
If that does not work, then please return to these forums (http://supportforums.blackberry.com/rim/) and register an account so that we can provide you with direct assistance.
Hopefully it'll work for you! Good luck and let us know!
